Whirlpool WP6-904023 Dishwasher Drain Solenoid OEM Part

I called and talked to a customer service rep and she helped me troubleshoot the problem and order the correct part. She also sent me the pdf of the repair manual and I followed its instructions to replace the drain solenoid. It was a fairly easy repair. I wasn't sure if I would need the water level control switch, but I ordered it to be on the safe side. Turns out the original is still good.
